So I was rewatching the G5 movie just because why not and I noticed that roughly around the 2-1/2 minute mark the camera pans down stairs to the desk of Sunny's fathers before landing on him. However, this gives us a glimpse of his research into Equestria's past and on the wall we get to see a small portion of the world with Ponyville, Canterlot, and Cloudsdale. But, I noticed that Everfree Forest was right next to Ponyville unlike how it was presented in FiM where it was presented roughly underneath the town unlike in G5 where it's shown to be to tht right of Ponyville. Which leads me to think that A New Generation takes place in a sepreate timeline from Gen 4. Though it's worth pointing out in the episode Family Appreciation Day, Everfree is shown in the bottom right of Ponyville along with at the time of me posting this we haven't gotten the G5 TV show. Now there is a chance that I could be entirely wrong which is why I'd recommend taking this Theory with a grain of salt and if you have any other evidence to prove that I'm wrong please let me know.
